Pros and Cons of Steganography. If there are holes in it?

Question

Encryption

Good day...
(PS I ask you not to immediately throw tomatoes at me)
... I have a question, I will not hide right away that I chose the topic of steganography for my master's degree. But I don't really understand its strengths and weaknesses. I read a couple of 2 scientific articles in the field of steganography, but I still can’t give birth to novelty. I thought about encrypting the sound in the picture, but the main question is where can one find scientific novelty in the field of steganography? I ask for light, I will be glad to any sensible answer or reference to literature from a person who is at least somehow connected with this area.
In advance, I express my respect and gratitude.

Answer 1

You don’t understand the topic of the thesis very well - change the topic
Holes can be in the implementation
If MitM knows that there is something inside - the steg with plain text does not work Scientific
novelty in this topic needs to be searched long and hard
